我在从nodejs / express应用程序连接到在docker容器中运行的mongodb实例时遇到问题 . nodejs应用程序正在我的本地主机Mac OS X上运行 . 我正在使用Docker Toolbox在我的Mac上运行docker，而不是boot2docker .
我已经通过-p arg启用了端口转发到docker run .
docker run -p 27017:27017 --name test -d mongo:2.6
60b7f3cf658bc75ceca2eae074e5f694ec622f7487b6a2f36fa02edd4af68357
我可以看到它在运行 .
docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
60b7f3cf658b mongo:2.6 "/entrypoint.sh mongo" 9 minutes ago Up 9 minutes 0.0.0.0:27017->27017/tcp test
如果我运行docker日志，我看到它正在侦听端口27017 .
docker logs test
mongod --help for help and startup options

当我尝试从express连接时，出现以下错误 .
my-app/node_modules/mongodb/lib/server.js:228
process.nextTick(function() { throw err; })
^
Error: connect ECONNREFUSED
at exports._errnoException (util.js:746:11)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1010:19)
现在，stackoverflow上有其他帖子引用了这个确切的东西 . 他们都说“通过-p arg启用端口转发”，我这样做了 . 但它仍然不会让我联系 .
我正在使用正确的端口和主机VM IP - 我可以通过常规的mongo shell工具从我的Mac连接到mongodb容器 .
还有一些奇怪的事情......
-
我可以通过mongo shell从我的Mac连接到容器mongodb就好了 . 当我运行docker logs test时，连接会显示出来 .
-
我也看到了日志中我的nodejs应用程序的连接，但是立即断开连接 .

我将回答我自己的问题，但不接受它 . 所以事实证明错误是由另一部分埋藏的nodejs代码引起的，该代码试图连接到mongodb：//127.0.0.1：27017 . 这个mongodb实例不存在，所以它抛出错误 .
我集中了mongodb配置，一切都是金色的 .
